Actually, some of those foods sound pretty good; I've sampled a few that were delicious. As for Louisiana's delicacy, the nutria (aka, the water hare), the story goes that in the 1920s the family that makes Tobasco sauce saw a way to diversify (apparently, making a world-renowned hot sauce wasn't enough for them) by importing and breeding nutria for their fur ("A nutria coat! For me? Oh, you shouldn't have!"). Then, as they tend to in Louisuana, a hurricane came along and wrecked all the cages and breeding areas. The nitria made their escape and have now been chewing away at the wetlands and breeding like rats (because, well, that's why they are) for almost 100 years.
